A bicycle or inverted pendulum can be balanced, that is kept nearly upright, by accelerating the base. This balance is achieved by steering on a bicycle. Simultaneously one can also control the lateral position of the base: changing of the track line of a bike or the position of hand under a balanced stick. We show here with theory and experiment that if the balance problem is removed, by making the system neutrally stable for balance, one cannot simultaneously maintain balance and control the… Expand
A Narrow-Track Tilting Tricycle With Variable Stability That the Rider Can Control Manually
This work presents a tilting tricycle with variable stability that the rider can control manually, and presents the titling linkage that implements this functionality, a mathematical model and the stability eigenvalues it produces, and confirmation of the model with a ridable physical prototype.

A Bicycle Can Be Self-Stable Without Gyroscopic or Caster Effects
This work built a bicycle with extra counter-rotating wheels (canceling the wheel spin angular momentum) and with its front-wheel ground-contact forward of the steer axis (making the trailing distance negative) and shows that various design variables, like the front mass location and the steeraxis tilt, contribute to stability in complex interacting ways.

A controller is derived which, using steering and rear-wheel torque, causes a model of a riderless bicycle to recover its balance from a near fall as well as converge to a time parameterized path in the ground plane. Expand
Guided Optimization for Balanced Locomotion
A method of using guiding forces to allow progressive learning of control actions for balanced locomotion is presented and involves using a “hand of God” to facilitate balance while the basic actions of a desired motion are learned. Expand
Direct and Steering Tilt Robust Control of Narrow Vehicles
Multivariable control tools (H2 methodology) are used to design, in a systematic way, lateral assistance controllers driving DTC, STC, or both DTC/STC systems robust to longitudinal speed variations. Expand
Modelling and analysis of the dynamics of a tilting three-wheeled vehicle
To understand the handling behaviour of a three-wheeled tilting vehicle, models of the vehicle with different level of detail, corresponding to specific fields of investigation, have been developed.Expand
An Active Roll-Moment Control Strategy for Narrow Tilting Commuter Vehicles
SUMMARY An automatic tilt control strategy for a narrow commuter vehicle is described. Such a vehicle would be enclosed like a conventional car but would bank into turns like a motorcycle and so itExpand
A fundamental investigation of tilt control systems for narrow commuter vehicles
One way of addressing traffic congestion is by efficiently utilizing the existing highway infrastructure. Narrow tilting vehicles that need a reduced width lane can be part of the solution if theyExpand
Effects of physical guidance on short-term learning of walking on a narrow beam.
The results suggest that physical assistance can hinder motor learning of walking balance, assistance appears less detrimental for more difficult tasks, and task-specific dynamics are important to learning independent of error experience. Expand
